Aircraft cabin module for passengers

ABSTRACT

An aircraft cabin module for passengers that includes two transverse walls extending from a longitudinal cabin wall up to a longitudinal aisle, at least one of the transverse walls including a transparent portion. A longitudinal wall separates the cabin module from the aisle. At least one service module is arranged between the two transverse walls, more or less symmetrically in relation to a transverse median plane, defining with the walls of the module two contiguous personal spaces. An access is provided from the aisle to each personal space, and at least one seat is provided in each personal space, each seat having at least one configuration in which it is positioned parallel to the cabin wall. Each personal space includes elements capable of forming a bedding surface for at least one passenger.

This invention relates to a cabin module for an aircraft.

Present-day aircraft offer different classes of comfort for theirpassengers. Accordingly, there are more or less comfortable seats(reclining backs, seats with a support provided for the legs, seatsconvertible into a bed, etc . . . ). The space allotted to eachpassenger itself is greater or lesser depending on the class.

Travelers thus may enjoy a considerable sleeping-arrangement comfort butdo not have, as is the case, for example, in a sleeper train, anenclosed private space.

This is explained by the safety constraints that exist on board anaircraft. Among these constraints, the following will be noted. Thepassengers must take off and land in seated position, in the directionof movement of the airplane or in the opposite direction. In addition,during these stages of take-off and landing, the crew, itself alsosettled sitting on a seat positioned longitudinally in relation to themovement of the airplane, must be able to keep an eye on most of thepassengers, in particular to see that everything is going well and that,for example, no passenger stands up during these stages of take-off andlanding.

To date, therefore, it has been thought that the implementation ofindividual compartments for one or more passengers was not suitable foran aircraft.

The purpose of this invention, however, is to provide a cabin module foran aircraft making it possible to re-create a space comparable to acompartment such as exists in sleeper trains. Of course, such a modulemust meet the safety standards established for civil aviation.

To this end, it proposes an aircraft cabin module comprising:

-   -   two transverse walls extending from one longitudinal cabin wall        to a longitudinal aisle,    -   a longitudinal wall separating the cabin module from the aisle,    -   at least one service module arranged between the two transverse        walls, more or less symmetrically in relation to a transverse        median plane, defining with the walls of the module two        contiguous personal spaces,    -   an access from the aisle to each personal space,    -   at least one seat in each personal space, each seat having at        least one configuration in which it is positioned parallel to        the cabin wall,    -   each personal space comprising elements capable of forming a        bedding surface for at least one passenger.

Such a module is compatible with the constraints existing in anaircraft, with respect to size as well as safety.

In order that the passengers may take a seat in the cabin module duringthe stages of take-off and landing while being visible to the commercialflight crew, it advantageously is provided that at least one of thetransverse walls comprises a transparent section.

The service module advantageously is arranged along the aisle, beingseparated from each transverse wall by a means of an access from theaisle to the module.

In a first embodiment of a module according to the invention, one seatin each personal space is of a convertible type and constitutes the saidelements capable of forming the bedding surface. In this case, the seatadvantageously is set up pivoting around a vertical axis in such mannerthat the bedding surface can be positioned crosswise.

In another embodiment, the elements capable of forming a bedding surfacecomprise, for example, a panel set up pivoting between a more or lessvertical position turned up against the service module and a more orless horizontal turned-down position. In this other embodiment, theelements capable of forming a bedding surface further comprise, forexample, a more or less horizontal support surface arranged along thecabin wall and cooperating with the pivoting panel when the latter is inturned-down position to form the bedding surface. It can be providedthat this support surface forms a seat possibly equipped with a back.

In a variation, a second seat is provided in each personal space. Thissecond seat can be a foldaway or other seat, and preferably ispositioned perpendicular to the cabin wall against same. In the lattercase, a corner seat can be arranged between the two seats in order toconnect them and thus form a corner banquette.

A preferred mode of embodiment provides that a movable or removablepartition is available to separate the two personal spaces at will,extending between the cabin wall and the opposite longitudinal wall.This partition advantageously is made up of several telescopic sectionsextensible transversely, the latter preferably folding back toward theservice module when the service module is centered in relation to thetransverse walls and arranged along a longitudinal wall. A housing thenadvantageously is provided in the service module to accommodate thetelescopic sections in folded-back position. This housing isimplemented, for example, in a transverse separation wall of the servicemodule. The same as the transverse walls of the module, the movablepartition itself also can comprise a transparent portion.

The transparent portions implemented in the transverse walls and in apossible movable partition preferably can be obscured. Thus, during thestages of take-off and landing, the transparent portions remaintransparent, and during cruising, these portions are obscured. Apreferred mode of embodiment provides that at least one transparentportion comprises a liquid crystal layer combined with means forsubjecting this liquid crystal layer to a difference of electricpotential, this layer being opaque or translucent depending on thedifference of potential applied. It also can be provided that at leastone transparent portion is equipped with a shade or similar element.

The service module is, for example, a bathroom facility having at leastone water source. The bathroom facility can be equipped with a centralwashbasin and/or a shower. It also comprises, for example, two accessdoors, each personal space comprising a door for access to the bathroomfacility. In the latter case, the bathroom facility advantageouslyincludes a washbasin for each personal space. Each washbasin then, forexample, is movable between a retracted position inside the bathroomfacility and an extended position outside the bathroom facility. In thiscase, the opening of the door for access to the bathroom facilityadvantageously controls the changeover of the washbasin from itsretracted position to its extended position.

The service module also can be a storage space, or else a medical-caremodule, or else a pantry unit equipped for the passengers' refreshment,or . . . etc. This module can be intended for the use of the passengerstraveling in the cabin module, or of the commercial flight personnel, oreven of third parties (physicians, . . . ).

The transverse walls, the service module and the seat at least one innumber are preferably each equipped with fastening means for theirattachment on longitudinal attachment rails arranged in the floor of thecabin. Such rails almost always are provided in airplanes intended forthe transport of passengers in order to make possible the attachment ofseats. The fastening means used for the elements making up a moduleaccording to the invention will be, for example, the same as thosecustomarily used for the attachment of seats, with a possibleadaptation.

By way of example, a module according to the invention has a length inthe longitudinal direction ranging between 2.0 m and 4.0 m and a widthon the floor, in the transverse direction, ranging between 2.3 m and 3.5m.

This invention also relates to a series of modules such as describedhereinabove, aligned one beside the other along a longitudinal aisle,characterized in that each transverse module wall, possibly except for atransverse wall located at one end of the series of modules, comprises atransparent portion and in that the transparent portions are aligned.

In such a series, the said seat of each module of the series having aconfiguration in which it is positioned parallel to the aisle preferablyis more or less in alignment with the transparent portions.

This invention also relates to an aircraft cabin section, characterizedin that it comprises at least one module such as described above. Thisaircraft cabin section comprises, for example, a central aisle on eitherside of which there is at least one module.

Finally, this invention relates to an aircraft, characterized in that itcomprises at least one module according to the invention.

Details and advantages of the invention will emerge more clearly fromthe description which follows, presented with reference to the attachedschematic drawing, on which:

FIG. 1 shows, in a view from above, a series of six cabin modulesaccording to the invention,

FIG. 2 shows in perspective an embodiment of a cabin module according tothe invention,

FIG. 3 shows in perspective another embodiment of a cabin moduleaccording to the invention, and

FIG. 4 shows schematically in cross section an airplane cabin sectionequipped with cabin modules according to the invention.

FIG. 1 depicts schematically the habitable space of a section of anairplane cabin. This section is located longitudinally between twosuccessive emergency exits 2. A longitudinal cabin wall 4 delimits thisspace on both sides of the airplane. Windows 6 are implemented in eachcabin wall 4. An aisle 8 extends longitudinally in the center of thecabin section. On either side of this aisle 8 there are, in each case,three modules 10 each intended to accommodate two passengers. The aisle8 is separated from each module 10 by a longitudinal wall.

The length of the aisle 8 is, for example, approximately 9 m, and itswidth approximately 0.75 m. Each module 10 then has a length, in thelongitudinal direction, of approximately 2.90 m. In the transversedirection, the width of a module 10 is, for example, approximately 2.70m.

Each module 10 is delimited on the one hand by a floor corresponding tothe floor of the cabin and by a ceiling, and on the other hand by theaisle 8, the cabin wall 4 and two transverse walls 12. In certain cases,as for example on FIGS. 2 and 4, the ceiling can consist of the cabinwall 4, because the latter has a circular cylindrical shape. The Figuresof the drawing depict modules 10 inside a long mail airplane having twodecks. FIGS. 1, 2 and 4 depict modules located on the upper deck, whileFIG. 3 depicts a module located on the lower deck. In the modulessituated on the upper deck, the ceiling follows the shape of the cabinsection, which is rounded, the cabin section being of a general circularcylindrical shape.

Each module 10 is equipped with a lavatory 14, seats and two beds. Themodule 10 is accessed from the aisle 8 by two doors 16 arranged oneither side of the lavatory 14, in each case between the latter and atransverse wall 12. Each module 10 is more or less symmetrical inrelation to a transverse median plane parallel to the transverse walls12 and positioned at an equal distance from the latter. Thus one moduleis formed from two half-modules each intended for one passenger anddefining a personal space for the latter. Each half-module is equippedwith a pivoting seat 18, a second seat and a bed.

Each lavatory 14 is of an overall parallelepipedal shape. It has twolarge longitudinal walls and two small transverse walls. It is equippedwith a washbasin 20. The lavatory 14 is accessed by two doors 22implemented in the small transverse walls of the lavatory. Thus is itpossible to access the lavatory 14 of a module from each of thehalf-modules thereof.

Each bed depicted on FIG. 1 is implemented in two parts, as can be seenon FIG. 4. A first part 24 is set up pivoting around a horizontal axis26 and a second stationary part 28 is arranged along the cabin wall 4.The first part 24 pivots between a vertical turned-up position along thelongitudinal wall of the lavatory 14 situated inside the module 10 and ahorizontal turned-down position in which it extends from the lavatory 14toward the cabin wall 4 up to the stationary part 28.

When the pivoting first part 24 is in its turned-up position, thestationary part 28 also can be used as a seat for a visitor. If theroundness of the cabin wall 4 does not make it possible to use thisstationary part 28 of the bed as a seat, it is possible to place anotherseat 30 in front of the stationary part 28 of the bed. This seat 30 thenhas, for example, a back which can be folded so as not to hinder theswinging motion of the pivoting first part 24 of the bed until it is inits horizontal position.

In each module 10 depicted on FIG. 1, there are two pivoting seats 18,one in each personal space. These seats can pivot 90° (at least) so asto be able to be positioned longitudinally, in particular for the stagesof take-off and landing of the airplane, and be positioned transverselyaccording to the desire of the passenger during flight. Certain seats 18of FIG. 1 are depicted in a longitudinal position, while others aredepicted in a transverse position.

The presence of foldaway seats 32 also is noted in the modules 10 ofFIG. 1. These preferably are arranged along a transverse wall 12. Thusthey are accessible even when the bed is horizontal. In certain modules10, a table 34 also is depicted. This table 34 can serve as a base forthe pivoting part 24 of the bed when the latter is in its turned-downposition. Then one need only choose the height of the table judiciouslyso that it supports the movable part 24 of the bed in horizontalposition.

FIG. 2 shows in perspective, with more details, an interior layout of amodule 10. It concerns a module different from those depicted on FIG. 1.The same references, however, are used to designate similar elements.

Accordingly in this module 10 there is a lavatory 14 arranged along alongitudinal wall between two doors 16, a pivoting seat 18 and a bed intwo parts. The module also is delimited by two transverse walls 12 andthe cabin wall 4. One transverse wall 12, however, and the cabin wall 4have not been depicted on this FIG. 2 in order to make it possible tobetter visualize the interior of the module 10.

The bed is of a configuration slightly different from that described inreference to FIG. 1. Here there is a pivoting part 24 turning up in avertical position against the lavatory 14 cooperating with another part36 to form the bed. In the case of this Figure, the other part 36 of thebed also is pivoting. It pivots around a horizontal axis parallel to thepivoting axis 26 of the pivoting part 24 which is more or less longerthan the complementary part 36. This part 36 of the bed can serve as afoldaway seat when the pivoting part 24 of the bed is turned up againstthe lavatory 14. It thus constitutes a second available seat within eachpersonal space inside module 10.

On FIGS. 2 and 3, there is noted in particular the presence of a movablepartition 38, parallel to the transverse walls 12 and separating the twopersonal spaces of the module 10. It concerns a telescopic partitionimplemented in several segments 40. In folded-up position, the segments40 are superposed on each other and are housed in the lavatory 14. Ahousing 42 is provided therein for this purpose.

In the two examples of implementation of a movable partition 38 depictedin the drawing, the segments 40 fold up, sliding on the floor so as tobe stored in their housing 42. It also may be planned to have asuspended movable partition which slides along a rail implemented on theceiling. In the configuration of FIG. 2, in which the ceiling is nothorizontal, the partition 38 then could have elements in the form ofdisk portions. In order to come into housing 42, these disk portionswould pivot around a horizontal axis close to the floor and to thehousing 42.

Housing 42 is implemented in a transverse wall which divides thelavatory 14 in two. This lavatory then is equipped here with two foldingwashbasins 20′. When the access door 22 of a personal space of module 10to the lavatory 14 is closed, the washbasin 20′ is turned up to verticalposition in the lavatory 14, and when the door 22 is opened, thewashbasin 20′ can be turned down and assumes a horizontal position,projecting outside the lavatory 14. The passenger using the washbasin20′ thus has more space because he does not have to go inside thelavatory 14.

The transverse walls 12 here all are equipped with a transparent portion44, thus making it possible for a member of the airplane crew to keep aneye on the passenger(s) located in the module 10, in particular duringthe stages of take-off and landing of the airplane. This transparentportion 44 is in the form of a horizontal strip centered atapproximately ⅔ of the height of the transverse wall 12. As may be seenon FIG. 1, when several modules 10 are aligned, provision is made toalign the transparent portions 44 so that a member of the crew seated inline with the modules can see inside each one of the latter and thusattend to the safety of the passengers located in the modules (cf. FIG.1), in particular during the stages of take-off and landing of theairplane. During these stages, the passengers are settled in a seatpositioned longitudinally (and equipped with a safety belt). Thetransparent portions 44 then are positioned on the transverse walls 12so as to see these seats, at least in part. There is an alignment,therefore, between the transparent portions 44 and the seats intended toaccommodate the passengers during the stages of take-off and landing.

As depicted in particular on FIG. 1, provision can be made in thetransverse walls 12 located near an emergency exit 2, for a recess toaccommodate a seat for a steward or stewardess during the stages oftake-off and landing or else even during evacuation of the aircraft.

For a transverse wall 12 located at the end of a line-up of modules 10,it can be pointless to provide a transparent portion 44 or else even inthe case of an isolated module, only one transparent portion 44 can becontemplated. In practice, however, it is preferable to have atransparent portion on all the transverse walls 12.

During flight, these transparent portions advantageously are able to bemade opaque or obscured. Different means can be used to this end. Forexample, provision can be made for shades, blinds, curtains, shutters,or similar elements. Each passenger in his module then can choose toobscure or not to obscure the transparent wall 44 of his personal space.In a preferred embodiment, the transparent portions 44 comprise a liquidcrystal layer and means making it possible to subject this layer to adifference of electric potential. These liquid crystals have theproperty of becoming opaque when they are positioned in a certainmanner, this positioning being obtained by electric excitation. Duringthe stages of take-off and landing, the transparent portions 44 are suchthat the crew can see the passengers inside the modules, while duringthe rest of the flight these transparent portions are made opaque.

FIG. 3 shows another possibility for layout of a module 10. In the caseof this format, as indicated above, the module 10 is situated on thelower deck of the airplane. The cabin wall 4 then is approximatelyvertical. Provision then can be made for baggage compartments 46 in thetop portion of the cabin wall 4. It also is possible to make provisionfor storage space in the lavatory 14 or else along the cabin wall in lowposition.

The seat 18 intended to accommodate the passenger during the stages oftake-off and landing is not pivoting here, but remains stationary. It issupplemented by a corner seat 48 and by the portion of the bed arrangedon the cabin wall 4 side to form a corner banquette.

In all these variations of embodiment described hereinabove, the variouselements making up each module 10 (the transverse walls 12, the seats,the lavatory 14, etc . . . ) are fastened to the floor on attachmentrails. Used here are the attachment rails which are provided for theattachment of seats in every airplane intended for transport ofpassengers. A series of longitudinal rails is provided throughout thewidth of the cabin. Regularly spaced anchoring points (usually everyinch, or with a distance of 2.54 cm) along each rail are provided forattachment of the seats. The means of attachment for the variouselements making up the modules are identical to those classically usedfor the fastening of seats on the rails.

This invention is not limited by the embodiments described hereinaboveby way of nonrestrictive examples. It also relates to all the variationsof embodiment within the reach of the individual skilled in the art, inthe context of the claims hereinbelow.

Thus, for example, numerous outfitting variations can be provided in themodules.

The seat intended to accommodate the passenger during the stages oftake-off and landing and arranged longitudinally during these stages canbe, for example, a seat convertible to a bed. In the case of thisformat, it then is not necessary to provide a separate bedding surface.This seat also can be moved around in the module. It was seen above thatthis seat could pivot, but provision also can be made so that it can bemoved.

The description presented hereinabove is given with reference to anairplane comprising two decks, which implies for each deck anunder-ceiling height for each deck which is limited. Accordingly, theembodiments described provide for a bed in two parts. With a greaterunder-ceiling height, however, having a bed with a sole part also couldbe contemplated.

The layout of the lavatory can be different from what is describedhereinabove. Outfitting this bathroom space with a shower or else even aWC can be contemplated.

It is possible to provide a different facility instead of the lavatory.This space can be used, for example, as a storage space, for thepersonal effects of the passengers traveling in the corresponding cabinmodule, or else for storage for the commercial flight personnel. In thelatter case, storing trolleys (or carts) in these spaces can becontemplated. This then makes it possible to make room at the sitecustomarily provided for the storage of these trolleys and to put inseating space for other travelers. This space also can be developed as apantry unit (generally designated by the English term “galley”).Preparing a special dish at the request of the passenger traveling inthe cabin module then can be contemplated. Same then can be prepared onthe spot and served immediately.

The cabin module also may be used for the repatriation of an ill orinjured person. In this case, the lavatory described aboveadvantageously is replaced by an area containing medical apparatus.

The lavatory or any service module, is not inevitably arranged along theaisle, or centered in relation to the two transverse walls of themodule. This service module, for example a lavatory, also could belocated along the cabin wall. In this case, this service module isprovided more for the use of the passengers traveling in the cabinmodule.

Providing two service modules, one in each personal space of the cabinmodule, likewise can be contemplated. These service modules thenpreferably are arranged symmetrically in relation to a transverse medianplane of the cabin module. These service modules then, for example, caneach be arranged in a corner of the cabin module.

The movable partitions described do not comprise a transparent portion.As a matter of fact, provision is made to retract them into theirhousing during the stages of take-off and landing. Nonetheless, if sucha movable partition is to be able to remain closed during these stagesof take-off and landing, a transparent portion, aligned with thetransparent portions of the transverse walls, preferably will beprovided.
